Frequently asked questions

Technical SEO focuses on optimising the backend structure and performance of your website to improve its visibility in search engines. It involves tasks like enhancing site speed, ensuring mobile-friendliness, fixing crawl errors, and implementing structured data. These improvements help search engines index your site efficiently while providing a seamless user experience.

Choosing the right technical SEO agency means looking for a team with a solid track record of success, proven expertise in resolving complex issues, and the ability to communicate their strategies clearly. It’s essential to find an agency that aligns with your goals, provides measurable results, and offers tailored solutions to enhance your site’s performance and search engine visibility.

A technical SEO audit is a comprehensive analysis of a website’s backend infrastructure and technical elements to identify issues affecting its search engine performance. This audit focuses on areas like site speed, crawlability, mobile-friendliness, URL structure, security (e.g., HTTPS), and indexing. By pinpointing and resolving these issues, a technical SEO audit ensures that search engines can effectively crawl, index, and rank your website, while also improving user experience and laying the groundwork for higher organic search visibility.

Collaborating with a technical SEO agency involves a strategic partnership to enhance your website’s performance. Start by identifying your goals—whether it’s improving site speed, fixing crawl errors, or boosting rankings. Share your website’s analytics, audit reports, and access to tools like Google Search Console to give the agency a clear understanding of your site’s current state.

Communication is key—ensure regular updates and reports to track progress. Be open to implementing their recommendations, from technical fixes to structural improvements, as their expertise is crucial for long-term success. A good agency will guide you through the process while keeping you informed and involved at every stage.

Technical SEO focuses on the backend of your website, ensuring it’s optimised for search engine crawlers and providing a seamless user experience. This includes tasks like improving site speed, mobile-friendliness, fixing crawl errors, implementing structured data, and ensuring proper indexing. It’s all about making your site’s infrastructure efficient and accessible to search engines.

Non-technical SEO, on the other hand, revolves around on-page and off-page strategies to enhance your site’s visibility. This includes creating quality content, optimising keywords, building backlinks, improving user engagement, and managing social signals. It’s more about content and reputation, whereas technical SEO handles the functional foundation that supports these efforts. Both are essential for a strong SEO strategy.

SEO and PPC complement each other by maximising online visibility. PPC gives immediate results, while SEO builds a strong, lasting foundation. Combined, they provide flexibility and resilience in search rankings.

Our team is committed to transparency and we never hide behind confusing metrics and jargon. We’re confident in our ability to deliver results that translate into a stronger online presence for your business.

The time it takes to see results from technical SEO can vary depending on the scope of the issues being addressed and the size of your website. For smaller fixes, such as resolving crawl errors or implementing structured data, improvements can often be seen within a few weeks as search engines recrawl your site.

For larger, more complex changes—like enhancing site speed, fixing mobile usability issues, or restructuring large ecommerce sites—it can take 3 to 6 months to see significant results as search engines fully process and re-evaluate your site.

Oh, and she’s a bit of a gamer, too—whether she’s getting lost in Sims 4 or collecting coins in Mario, Alice knows how to balance work, creativity, and a bit of gaming nostalgia.
